Start by positioning a chair next to the crib.

Nights one, two, and three
Lay your child in their bed and stay close enough so you can reach from them from the chair.
Touch your child gently and use your voice to soothe; you can talk, shush, or sing. You can pat your child.
Your presence is key. If your child stands up, gently lay them back down. If they’re very upset, you can pick them up, but always remain next to the crib. When they’re soothed, lay them back down and sit back in your chair, providing comfort as needed. Repeat as necessary.
Remain in the chair until your child is fully asleep. Don’t rush off as soon as you see them close their eyes, as they are likely to wake instantly.

Nights four, five, six
Move the chair a little distance away from the crib.
Pop your child into the crib and move to the chair; you can talk, sing, or shush to soothe your child.
Try to remain in the chair as much as possible. If your child cries, try to stay in the chair and soothe with your voice.
If the cry becomes more urgent, you can go to your child to help soothe them, even picking them up if needed, remaining next to the crib. Always pop them back down into the crib and return to the chair when comforted. Tiptoe out of the room when they are settled.

Nights seven, eight, nine
Move the chair further away, right by the door if you can (don’t block your exit!).
Lay your child down as before and use your voice as needed to soothe and reassure.
Intervene as little as possible and stay in the chair as much as possible.
As soon as your child seems settled, tiptoe out of the room.

Moving forward
Try leaving the room after you have put your child into bed.
You can always come into the room as needed if your child needs help.
When they are soothed, leave the room again.

Remember to treat the night wake-ups the same, using the same way of helping your child to sleep and keeping the chair in the same position as the beginning of the night.
